A radiopaque, bioresorbable stent, created in situ

摘要

A fenestrated stent formed in a body lumen is provided which includes an article shaped to provide support to a section of a body lumen and allow biological material which would otherwise flow through the body lumen to flow through the article, the article being formed with fenestrations by delivering a fluent pre-stent composition to a mold space defined by a section of a body lumen and a fluent pre-stent composition delivery device having members which define the fenestrations, and transforming the fluent pre-stent composition to a non-fluent stent composition within the mold space.
